Humans have a storied and complicated relationship with drugs. Defined as chemical substances that cause a change in our physiology or psychology, many drugs are taken medicinally or accepted culturally, like caffeine, nicotine, and alcohol. But many drugs—including medicines and non-medicinal substances taken as drugs—are taken recreationally and can be abused. Each country and people have their own relationship to drugs, with some embracing the use of specific substances while others shun them outright. What are the most common drugs that are considered generally illicit in different parts of the world? Today’s graphics use data from the UN’s World Drug Report 2021 to highlight the most prevalent drug used in each country.

What Types of Common Drugs Are Tracked?

The World Drug Report looks explicitly at the supply and demand of the international illegal drug market, not including commonly legal substances like caffeine and alcohol. Drugs are grouped by class and type, with six main types of drugs found as the most prevalent drugs worldwide.

Cannabis*: Drugs derived from cannabis, including hemp. This category includes marijuana (dried flowers), hashish (resin), and other for various other parts of the plant or derived oils. Cocaine: Drugs derived from the leaves of coca plants. Labeled as either cocaine salts for powder form or crack for cocaine processed with baking soda and water into rock form. Opioids: Includes opiates which are derived directly from the opium poppy plant, including morphine, codeine, and heroin, as well as synthetic alkaloids. Amphetamine-type Stimulants (ATS): Amphetamine and drugs derived from amphetamine, including meth (also known as speed), MDMA, and ecstasy. Sedatives and Tranquilizers: Includes other drugs whose main purpose is to reduce energy, excitement, or anxiety, as well as drugs used primarily to initiate or help with sleep (also called hypnotics). Solvents and Inhalants: Gases or chemicals that can cause intoxication but are not intended to be drugs, including fuels, glues, and other industrial substances.

The report also tracked the prevalence of hallucinogens—psychoactive drugs which strongly affect the mind and cause a “trip”—but no hallucinogens ranked as the most prevalent drug in any one country. *Editor’s note: Recreational cannabis is legal in five countries, and some non-federal jurisdictions (i.e. states). However, in the context of this report, it was included because it is still widely illicit in most countries globally.

The Most Prevalent Drug in Each Country

According to the report, 275 million people used drugs worldwide in 2020. Between the ages of 15–64, around 5.5% of the global population used drugs at least once. Many countries grouped different types of the same drug class together, and a few like Saudi Arabia and North Macedonia had multiple different drug types listed as the most prevalent. But across the board, cannabis was the most commonly prevalent drug used in 107 listed countries and territories: How prevalent is cannabis worldwide? 72 locations or more than two-thirds of those reporting listed cannabis as the most prevalent drug. Unsurprisingly these include countries that have legalized recreational cannabis: Canada, Georgia, Mexico, South Africa, and Uruguay.

How Common Are Opioids and Other Drugs?

Though the global prevalence of cannabis is unsurprising, especially as it becomes legalized and accepted in more countries, other drugs also have strong footholds. Opioids (14 locations) were the most prevalent drugs in the Middle-East, South and Central Asia, including in India and Iran. Notably, Afghanistan is the world’s largest producer of opium, supplying more than 90% of illicit heroin globally. Amphetamine-type drugs (9 locations) were the third-most common drugs overall, mainly in East Asia. Methamphetamine was the reported most prevalent drug in China, South Korea, and Japan, while amphetamine was only the most common drug in Bangladesh. However, it’s important to note that illicit drug usage is tough to track. Asian countries where cannabis is less frequently found (or reported) might understate its usage. At the same time, the opioid epidemic in the U.S. and Canada reflects high opioid usage in the West. As some drugs become more widespread and others face a renewed “war,” the landscape is certain to shift over the next few years. on Are wealth and prosperity legitimate measures of happiness? How about safety and health outcomes? In the West, we view democracy as a key component to happiness, yet there are countries under authoritarian rule that score high in the Happiness Index. Questions like these make “ranking happiness” a particularly challenging puzzle, but also one worth pursuing. If policymakers have a clearer picture of what conditions can foster happiness, they can enact policies that can improve the lives of people living their jurisdictions. The map above is a global snapshot of life satisfaction around the world. It utilizes the World Happiness Report—an annual survey of how satisfied citizens are worldwide—to map out the world’s happiest and least happy countries. To create the index the map is based on, researchers simply asked people how satisfied they are with their lives. Scores were assigned using these self-reported answers from people living within various countries, as well as quality of life factors. While there may be no perfect measure of happiness around the world, the report is a robust and transparent attempt to understand happiness at the global level. For more detailed notes on the report’s methodology and more, we recommend viewing the info box at the end of this article. Now, let’s look at the world’s happiest countries in 2023.

Global Happiness, by Country

Global happiness currently averages out to 5.5 out of 10, a decrease of 0.1 from last year. Below is a look at every country’s score: Note: Scores have been rounded to the first decimal place. European countries make up the bulk of the top 10, with Israel (#4) and New Zealand (#10) also making it into the top ranks. Finland sits at the very top of the ranking for the sixth year in a row. Now let’s look at the world’s happiest countries on a more regional basis.

North America

Current Mood: Happy (6.3)

North America’s happiness score averages out to 6.3/10. The happiest country in the region is Canada, slightly beating out the United States. However, the scores of both countries have actually decreased from last year. It’s difficult to pinpoint why citizens feel less satisfied, but inflation, economic uncertainty, and many other factors could play a role. The only countries to see improvement in North America were Nicaragua and Jamaica. Although a more recent development, many Jamaicans could be experiencing even more happiness in the near future, with a recent announcement of plans to increase the minimum wage by 44%.

South America

Current Mood: Content (5.8)

South America’s average score is 5.8. Although Venezuela is the continent’s least happy country, its score actually improved from 4.9 to 5.2. That said, the ongoing humanitarian and economic crisis is not likely to instill much hope into the average Venezuelan. Over 6.8 million people have fled the struggling nation since 2014. The two countries in the region with decreased scores were Brazil and Colombia, where citizens have reported feeling worse compared to the year before.

Europe

Current Mood: Happy (6.4)
Europe has some of the world’s happiest countries, with an average regional score of 6.4. Nordic countries like Finland, Sweden, and Iceland repeatedly report high scores, meaning people in these countries feel extremely satisfied with their lives. Despite fending off an invasion, Ukrainians saw no diminishment of their happiness year-over-year, and many are feeling resilient and purposeful in their fight for freedom. Interestingly, Russia’s score actually increased slightly compared to last year, going from 5.5 to 5.7.

East Asia and Oceania

Current Mood: Neutral (5.6)

East Asia and Oceania’s collective average is 5.6. Oceania alone, however, would have the highest regional score in the world, at 7.1. Bucking conventional wisdom—at least in the West—China has seen a noteworthy bump (+0.6) in its score in recent years. Across the strait, Taiwan records the second highest score in East Asia, after Singapore. India once again has the lowest happiness score in its region. The country’s score has dropped -0.7 over the past decade.

Central Asia and The Middle East

Current Mood: It’s Complicated (5.2)

The average score in the Middle East and Central Asia is 5.2, and the array of happiness scores is wider than in any other region. Afghanistan is the world’s least happy country, with citizens having reported extremely low levels of life satisfaction. Since the Taliban takeover, life has become objectively worse for Afghans, particularly women. There is a lot of conflict in the region. Citizens of Armenia face particular tension with neighboring Azerbaijan, whose score was not recorded for this year. Conflicts in the Nagorno-Karabakh region have led to hundreds of deaths since 2020 and cause daily struggle for those who live in the disputed territory. Iran is still under economic sanctions and faces ongoing tensions with the U.S. and Israel. Some countries, like Syria and Yemen, are so destabilized that no data is available. Still, there are bright spots as well. Israel has one of the world’s happiest countries with a top 10 score this year, and Saudi Arabia and the UAE have scores on par with many European countries.

Africa

Current Mood: Unhappy (4.4)

The least happy region, Africa, averages out to a score of 4.4, and there is a lot of regional variation. The highest score in Africa goes to the island nation of Mauritius. In addition to the country’s natural beauty and stability, there is growing economic opportunity. Mauritius is classified as an upper-middle-income country by World Bank, and is one of the fastest growing high-income markets in the world. Sierra Leone has the lowest score of African countries that were included in the index, followed by Zimbabwe and the Democratic Republic of the Congo. It’s worth noting, there are a few data gaps in the region, including Burundi, which is currently the poorest country in the world. Source: The World Happiness Report which leverages data from the Gallup World Poll. Methodology: A nationally representative group of approximately 1,000 people is asked a series of questions relating to their life satisfaction, as well as positive and negative emotions they are experiencing. The life evaluation question is based on the Cantril ladder, wherein the top of the ladder represents the best possible life for a person (a score of 10/10) and on the flipside, the worst possible life (scored as 0/10). The main takeaway is that the scores result from self-reported answers by citizens of each of these countries. The results received a confidence interval of 95%, meaning that there is a 95% chance that the answers and population surveyed represent the average. As well, scores are averaged over the past three years in order to increase the sample size of respondents in each country. Criticisms: Critics of the World Happiness Report point out that survey questions measure satisfaction with socioeconomic conditions as opposed to individual emotional happiness. As well, there are myriad cultural differences around the world that influence how people think about happiness and life satisfaction. Finally, there can be big differences in life satisfaction between groups within a country, which are averaged out even in a nationally representative group. The report does acknowledge inequality as a factor by measuring the “gap” between the most and least happy halves of each country.
